Why I built this

I'm Ferencz, and I had my second kidney transplant in March 2026.

After surgery, I was drowning in spreadsheets — tracking tacrolimus levels, creatinine trends, fluid intake, blood pressure, and a handful of medications with different schedules. I needed something simpler.

So I built Grafta for myself. Privacy was non-negotiable — my health data stays in my own Google Drive, not on someone else's server. Usability matters too — I fill this in every morning with one hand while holding coffee with the other.

If you're on a similar journey, I hope it helps you too.

Frequently asked questions

Is my health data really private?

Yes. Grafta stores everything in a Google Sheets file inside your own Google Drive. No health data ever touches our servers. We can't see your values even if we wanted to.

Is Grafta free?

Completely free, no credit card required. Grafta is a personal project, not a venture-backed startup chasing revenue.

What happens if Grafta disappears?

Your data stays in your Google Drive as a normal spreadsheet. You can open, edit, or share it with your doctor — no lock-in.

What can I track right now?

Medications (with schedules and adherence), creatinine and tacrolimus lab results, blood pressure, weight, temperature, water intake, and urine output. More labs are coming.

Can my doctor see my data?

Not automatically. You can share your Google Sheet with them, or use the built-in report generator to print a PDF summary for your next visit.

Do I need to install anything?

No. Grafta runs in your browser. On mobile you can add it to your home screen for an app-like experience — it works offline too.

What languages are supported?

English, Romanian, and Hungarian. You can switch any time from the language selector.
